I still haven't learnt how to install mods for this game.Nothing seems to be working. I'm not sure what I'm doing wrong but I can not get anything to work.

Are you using the Oblivion mod manager? Also make sure you are reading the mods instructions fully. Try installing one mod at a time and testing. Start with one mod, a big one you really want. Install it. If it works move onto something else. Make sure they aren't conflicting also.
